Osmosis In Potatoes

Investigate what effect different levels of concentration of sucrose reception have on the movement of water via osmosis in dust coat potato vinees. EQUIPMENT saccharose resolvent (0.2M, 0.4M, 0.6M, 0.8M, 1.0M) Distilled water (0.0M) Potatoes Cork rock drill Boiling undergrounds Boiling electron tube rack Stop measure Balance (0.0 decimal places) Tweezers Measuring cylinder Ruler method manage 6 pieces of potato with a cork bore bit and racetrack them to the alike length of approximately 5 cm (measure with a ruler) Measure out 25cm³ of water and separately of the sucrose issues, victimisation the measuring cylinder. The measurements for the resolves have to be perfect as to not change the outcome of the experiment. Pour into simmering tubes, talent the mingled concentrations. Label boiling tubes with concentration of sucrose solution count measurements of each potato tube ( hatful) on the par wholeelism and recruit in a suitable table. Always use the very(prenominal) balance to weigh the mass of the each tube as measurements may differ slightly between scales. The surface part of the potato tubes will be kept the same by having all the tubes the same size. They must be kept the same because the measurement of surface area exposed to the solution may chance on the rate of osmosis. Be sure to personal line of credit which strength solution is put in each.

Place potatoes in sucrose solution and leave for 30 minutes, using the stopwatch for accurate timings. shift potato tubes and pat off exorbitance sucrose solution with a pap er towel, in the regulate that they came ou! t of the boiling tubes as to not confuse which tube came from which solution. Take measurements of mass and length of each tube and temper appearance in a suitable table. This experiment should thence be reiterate to ensure a fair exam as the results give the bounce then be compared. . anticipation It could be predicted that as the concentration of the sucrose increases, the mass and length of the potato tube will decrease. The think behind this, is that the higher(prenominal) the concentration of sucrose in...If you want to win a bountiful essay, order it on our website: OrderCustomPaper.com
